This tutorial article I will no longer continue to update or maintain it, and I am completely open-sourcing it, allowing anyone to modify, use, and republish it as they see fit. However, please do not ask me any further questions regarding this tutorial article. I have been providing these educational resources for free all along, yet no one has been willing to sponsor or support me.
This article was translated using "DeepL Translator".
The main purpose of this tutorial is that in August this year, Google announced that new apps will be uploaded in AAB format instead of the APK and OBB file formats that have been used in the past.
＊ For more details, please refer to this Google announcement:
https://android-developers.googleblog.com/2021/06/the-future-of-android-app-bundles-is.html
In short, this tutorial will teach you to export to AAB format to get you on the Google Play Store release App, as well as the implementation of In-App Purchases and Admob ads.

■ Only
Put your exported RPG Maker MV/MZ project in the MyApplication\Only\src\main\assets\www folder.
Under Only, mouse right-click res → values → strings.
After selecting Open Translations Editor,
you can change app_name in Default Value to set your APP game name and other string parameters.
Select Build → Build Bundie(s) / APK(s) → Build APK(s) output.
After the output is finished, in the folder MyApplication\Only\build\outputs\apk\debug, you can find three apk files, just install Only-universal-debug.apk to your Android phone and play game.
■ IAP
Put the RPG Maker MV/MZ project you just exported Put it in the MyApplication\RPGAssets\src\main\assets folder.
In File → Project Structure… in Modules, modify the three parameters of Default Config, which are Application ID, Version Code and Version Name respectively.

And license key section can be found in the bottom left of Google Play Console under Monetization setup.
The test_mode setting is for test mode, but remember to set this to false when you publish in the Google Play Store.
The remaining five items are for the AdMob ads units, which are currently filled in as test ads units by default.
If you use AdMob ads units, remember to change them to the AdMob ads units of your own account.
And the use of AdMob ads here I will not explain in particular.
Finally, under Build → Generate Signed Bundle / APK…, select Android App Bundle and click Next.
Select Android App Bundle and click Next, then create or use your signature key.

■ Extra
● How to make RPG Maker MV support touch UI?
Add that although RPG Maker MV itself does not have a built-in button UI features for cell phone touch, but you can use the official TouchUI.js plugin to solve the problem of cell phone operation game.
And the TouchUI.js plugin is placed in the folder of D:\Steam\steamapps\common\RPG Maker MV\dlc\KadokawaPlugins_New\js\plugins.
● How do change the Splash image? (ex: Made by MV image.)
In MyApplication\IAP\src\main\res\drawable, replace logo.png with the image file of your own Splash.
If it is Only, the path is MyApplication\Only\src\main\res\drawable.
● How do I change the orientation of my Android phone screen to Portrait?
This will show you how to modify the display direction of your phone in Android Studio project, while the resolution setting of RPG Maker MV/MZ should not need me to teach you specially.
First of all, make changes in the files manifests/AndroidManifest.xml and res/layout/activity_main.xml respectively.
In the AndroidManifest.xml file, change "sensorLandscape" to "sensorPortrait" in the 21st code.
In the activity_main.xml file, switch to Design and change the parameter of orientation to vertical in main.
● Why does my RPG Maker MZ game keep stopping on a black screen when I play it on my Android device?
You can try changing the syntax around line 2109 in js/rmmz_managers.js in the project folder.
SceneManager.isGameActive = function() {
// [Note] We use "window.top" to support an iframe.
try {
return window.top.document.hasFocus();
} catch (e) {
// SecurityError
return true;
}
};
Modify to
SceneManager.isGameActive = function () { return true; };
